Ads-b compliance

Christopher Murphy · #1 01-21-2016, 01:25 PM

I just had my xponder (kt-76) re certified and the avionics tech was pushing me to start thinking about becoming ads-b compliant.

I haven't even begun to look into and now I suppose it's time to start.

The options he showed me were expensive and more expensive..

What's out there that replaces the transponder and encoder?? That is quality equipment, doesn't cost 1/2 the value of my airplane. I have a non waas GPS (klx135a).

Don't care about wx and traffic displays unless the increase in cost in minor
Don't want to fool with blue tooth or this talks to the iPad and this talks to the box in your pocket which has to have a cell signal...
Prefer TSOd radio equip

I have a dynon d10a but don't care about big EFIS displays or any other fancy stuff...

Anyone ...

Someone in another thread on this topic mentioned the Trig TT-31 as a slide-in replacement for the KT76.

EDIT: Seems you have to replace the tray to get ADS-B functionality. And, as airguy mentioned below, a WAAS GPS source - of course.

You'll still need a GPS receiver to feed high-quality data to the transponder after 2020 - might as well add that to the pile.

You've already got a D10, you could step that up to the Dynon 7" Skyview and use their transponder and GPS-2020 receiver puck and you're done.

Read the specs on the trig. Didn't really talk about the waas gps except that it's required in the U.S.

The tech recommended the stratus esg. By appareo about 1000$ more

The stratus esg. Has a built in waas gps. Takes a feed from the encoder and is 1090es extended mode s Squitter it's 3500$ not installed.

I'm thinking the dynon 7inch set up is a lot more?

The Navworx and Freeflight systems are the least expensive and will work with your existing transponder. Lots of discussion on these already exist here on the forum.

If you're thinking about the Pitts or RV4 ( both I assume are experimental) you might want to look at the Navworx ADS600 EXP . It's a UAT ( Universal Access Txmitr) up to xxx altitude. It will interface to your existing Xponder provide GPS and meet 2020 compliance. For around 1500 or maybe less if you don't want to see traffic or Wx. Be prepared to wait a while.

I read up on the navworx solution.
I assume these things have to be checked and certified like a transponder? Will avionics shops work on them?

What does the wifi feature do?
Didnt see anything about mode s

Mode s not required for 2020 compliance.

As far as I know, there is no change to certification. Just the transponder/pitot static system as before.

Mode S is only required if you plan to fly in Class A airspace (in the US). The feds are actually pushing for people that don't need S to use the 978/UAT band to reduce the load on the 1090 side, where all the big iron flies.
